详细合成路线

异丙醇上游产品

异丙醇下游产品

1.间接水合法：将含丙稀50%以上的原料气通入吸收塔，在50℃和低压下用75%-85%的浓硫酸进行吸收反应，生成硫酸氢异丙酯。加水将吸收液稀释到硫酸含量为35%后，在解吸塔中用低压蒸汽将硫酸氢异丙酯水解成异丙醇。经粗蒸塔馏到异丙醇与水的共沸组成，含异丙醇87%左右。再继续用蒸馏塔蒸浓到95%，用苯萃取、分离水后再蒸馏，可得含异丙醇99%以上的成品。

该法特点是对丙烯的纯度要求不高，而且丙烯转化率可达50%-60%，可减少精制费用。但耗用硫酸量大，而且存在设备腐蚀和40%的废硫酸的浓问题。

2.直接水合法：将丙烯和水分别加压到1.96MPa，并预热到200℃,混合后加入反应器,进行水合反应.反应器内装有磷酸硅藻土催化剂,反应温度为95℃,压力为0.96MPa，水与丙烯的摩尔比为0.7：1，丙烯的单程转化率为5.2%，选择性为99%。反应气体经中和换热后送到高压冷却器和高压分离器，气相中的异丙醇在回收塔中用脱离子水喷淋回收，末反应的气体经循环压缩机加压后循环使用（保持循环系统中丙烯含量85%）。液相为低浓度异丙醇（15%-17%），经粗蒸塔蒸馏得85%-87%的异丙醇水溶液，再经蒸馏塔蒸浓到95%，然后用苯萃取提浓到99%以上。

与丙烯硫酸水合法相比，本法不用硫酸，不存在腐蚀设备问题，工艺流程简单；但丙烯单程转化率低，丙烯循环量太大，而且要求原料丙烯纯度达99.5%。为了克服丙烯直接水合法的缺点，以95%的丙烯为原料，反应温度240-270℃，反应压力14.7-19.6MPa，水与丙烯的摩尔为水过量。丙烯转化率为60%-70%，异丙醇选择性为99%，异丙烯精馏制后纯度可达99.9%以上，副产物为二异丙醚。此外，采用分子筛催化丙烯水合制异丙醇也是非常有前途的改进工艺方法。

3.将含丙烯50%以上的原料气，在50℃和低压下用75%～85%的浓硫酸进行吸收反应，生成硫酸氢异丙酯。再将硫酸氢异丙酯水解成异丙醇。经粗蒸用蒸馏塔蒸浓到95%，再用苯萃取、分离水后再蒸馏，可得含异丙醇99%以上的成品。或者将丙烯和水分别加压到1.96MPa，并预热到200℃，混合后加入反应器，进行水合反应。反应气体经中和换热后送到高压冷却器和高压分离器，气相中的异丙醇在回收塔中用脱离子水喷淋回收，经粗蒸塔蒸馏得85%～87%的异丙醇水溶液，再经蒸馏塔蒸浓到95%，然后用苯萃取得99%以上的异丙醇。

4.以工业品异丙醇为原料，在每升原料中加入200g新鲜的氧化钙，进行回流，数小时后蒸馏，以除去大部分水，然后在所收集的馏出液中加入氢化钙、氧化钡、钙、无水硫酸铜或5A分子筛，充分振后，静置48h，分出固体干燥剂后蒸馏，即可得纯品。

5.以95%的丙烯和过量水为原料，在钨系催化剂（如硅酸钨）存在下，于240～270℃，14.7～19.6MPa条件下进行反应：

所得异丙醇，精制后纯度可达99.9%以上。

6.先将过量的丙烯和水分别加压至2MPa ，预热至200℃。然后混合，送入反应器反应，催化剂为磷酸硅藻土。控制反应温度195℃，压力维持2MPa，反应结束后，气体先经中和然后进行高压冷却冷凝并气液分离，未反应气体，可循环使用。所得液体为浓度较低的粗异丙醇。经二次蒸馏浓度达95%，然后用苯萃取提浓可达99%以上。
